Summary
Positron Emission Tomography (PET) imaging reveals early serotonergic signaling degeneration in Parkinson's disease (PD). This understanding aids in developing new treatments for motor and non-motor symptoms.
Area of Science:
- Neuroscience
- Molecular Imaging
- Neurology
Background:
- Parkinson's disease (PD) involves progressive degeneration of central monoaminergic pathways, notably serotonergic signaling.
- Serotonergic pathway dysfunction in striatal and extrastriatal regions is an early PD hallmark, linked to motor and non-motor symptoms.
Purpose of the Study:
- To review the current understanding and application of Positron Emission Tomography (PET) imaging in investigating serotonergic pathology in Parkinson's disease.
- To highlight the role of in vivo molecular imaging in understanding PD's biological changes and identifying therapeutic targets.
Main Methods:
- Utilizing Positron Emission Tomography (PET) molecular imaging techniques.
- Investigating in vivo biological changes and serotonergic pathology in PD patients and at-risk individuals.
Main Results:
- PET imaging has significantly advanced the in vivo investigation of PD's biological changes.
- It has elucidated the extent of serotonergic pathology in PD, offering insights into disease mechanisms.
Conclusions:
- Serotonergic imaging in PD is crucial for understanding pathology progression and identifying therapeutic targets.
- Future imaging studies will clarify the relevance of serotonergic pathways to PD and inform pharmacotherapy development.

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

1.1K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
